Improvement in door-buttons



UNITED STATES PATENT OEEIo ELBRIDGE J. STEELE, OF NEW BRITAIN,CONNECTICUT, ASSIGNOR TO THE TAYLOR MANUFACTURING COMPANY, OF SAMEPLACE.

IMPROVEMENT IN DOOR-BUTTONS.

Specification forming part of Letters Patent No. 152,774, dated July 7,1874; application filed March 3, 1874.

To all whom it may concern Be it known that I, ELBRIDGE J. STEELE, ofNew Britain, county of Hartford and State of Connecticut, have inventedcertain new and useful Improvements in Buttons for Doors, of which thefollowing is a specification The nature of my invention consists in thenovel combination and arrangement of a plate, button and wire spring toform a button for doors, show-cases, &c.; the spring, working in groovesin the shank of the button, thereby holds the button to the plate, andalso holds the button firmly at every quarter-revolution, to prevent itfrom being turned after being set, as will hereinafter be more fully setforth.

In order to enable otli'ers skilled in the art to which my inventionappertains to make and use the same, I will now proceed to. describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is aperspective view of my doorbutton. Fig. 2 is a bottom orinside view; and 1 ig. 3, a longitudinal section of the same.

A represents a cast metal plate, of any suitable dimensions, and of theform shown in the drawing, or any other form or shape desired. Thisplate is cast with a flange, a, around its edges, projecting on one sideonly, forming, as it were, a shallowbox or casing, within which, in thecenti r, near the outer side, is cast a stud, b. B represents thebutton, formed in any suitable shape, and cast with a short round shankor stem, d, in the center. This stem or shank d is passed through a holecast in the plate A, in the center, near the outer edge, the stemprojecting on the under side of the plate. In the circumference of theshank or stem d, immediately within or on the inside of the plate A, aremade grooves, was, forming four straight sides, as shown by dotted linesin Fig. 2. Around the stud b is wrapped a wire spring, h, the ends ofwhich cross each other, and are sprung into the grooves 00 :10 on thestem d. This spring serves a twofold purpose First, it holds the buttonB to the case or plate A, and prevents itsbeing removed from the same;second, it holds the button firmly at every'quarter of a'revolution, andprevents its becoming turned after being set. The plate A is fastened tothe door-frame by screws, through holes '5 i castin the plate.

I am aware that a door-button provided with a spring to keep the samefrom turning is not new, and hence I do not claim such broadly as myinvention. By my construction of the door-button no screw or bolt isnecessary to hold the button to the plate, the same spring whichprevents the button from turnin g holding the button to the case.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The combination of the flangedplate A with stud b, the button B, with stem or shank d, having grooves00 x, and the wire spring h, all constructed substantially as and forthe purposes herein set forth.

In testimony that I claim the foregoing as my invention, I hereuntoaflix my signature this 27th day of February, 1874.
